Happy Pi Day

From a friend: "Pi, Greek letter π, is the symbol for the ratio of the circumference of a circle to its diameter. Pi = 3.1415926535... Pi Day is celebrated by math enthusiasts around the world on March 14th.

“If, in a circle, a lineHits the center,and runs spine to spine,And the lines length is DThe circumference will beD times 3.14159.”

Last year we went all out. I sent greetings to my math loving nephew, made a pizza pi for dinner, we colored a pinwheel of the first 100 digits in pi.

Also, MIT sends out its acceptance letters the week of pi day. If you didn't plan accordingly you could instead join Europe in celebrating Pi Approximation Day 22/7(July 22nd)For some reason the others at Science co-op last year though I was odd.
